Tarquin As Benedikt mentioned, scraps are joined, not maps. If you join scraps, the maps that use those scraps will automatically show the join, so the maps themselves are not relevant to the joining process.
I have an example of a three cave system that we surveyed and subsequently joined in 2007-2008. The highlighted words are the names of the respective cave surveys. For one of the joins, we could use a simple (and recommended) scrap to scrap join, using scrap_ids; join GreenlinkUSumpsPlan_s2@Greenlink GreenlinkFPlan_s1@MiddleEarth -smooth on For the other pair of caves, I have lots of lines within each scrap that crossed from one to the other, so I had to use the more complicated line by line joining, that you seem to be trying to follow, using line_ids; join jpwall04@SwissM:end GUSwall02@Greenlink:end join jpwall03@SwissM:00 GUSwall01@Greenlink:0 join jpwall06@SwissM:end GUSwall03@Greenlink:0 join jpwall07@SwissM:end GUSwall04@Greenlink:end join uwall04@SwissM:0 swall02@Greenlink:end join secondwall01@SwissM:0 swall05@Greenlink:end Although looking at it now, with the benefit of 10 more years of experience, I wonder if I could have used a simpler scrap to scrap join, with the -count 3 option. [Refer to the description of join on page 40-41 of The Therion Book]. Depending on the details of your data structure, there may need to be subtle differences in the way you reference the scraps, but looking at your description below, I think the style of scrap referencing I have used should work for you (probably). If it does not, you could try removing the (highlighted) cave survey names.

My survey is split into several "caves", each of which has its own .th and .th2 file. In the .th file for each cave is a separate "map", so that the cave can be rendered separately. cave1.th: survey cave1 input "cave1 plan.th2" input "cave1 ee.th2" map cave1MP scrap1 scrap2 endmap centreline ... endcentreline endsurvey cave2.th: survey cave2 input "cave2 plan.th2" input "cave2 ee.th2" map cave2MP scrapa scrapb endmap centreline ... endcentreline endsurvey Then I have an overall file which combines the maps called allcaves.th: survey allcaves map allcavesMP cave1MP@cave1 cave2MP@cave2 join ____________ endmap centreline ... endcentreline endsurvey Imagine the two caves join in scrap1 (id "foo":0) and scrapb (id "bar":end), and I want to use a join command to make the scraps join neatly (I have already positioned the passage ends very close to each other). Could you please tell me the syntax needed to make the join command reference the correct points of the correct lines inside the correct scraps inside the correct maps? Every example of the "join" command I could find assumes you were trying to join scraps inside the same map, and did not show how to reference items in a sub-map. As a result, I have not been able to work out how to construct a valid join command for this situation. Many thanks for any information you can provide.
